Hello:
In this article: You will learn to Write or Read A Text File.

Let's Begin:
First Create a new project (ConsoleApp or WinApp).
And Make sure your program uses these namespaces:

Expand|Select|Wrap|Line Numbers

1. using System;
2. using System.IO;
3. using System.Diagnostics;
4.  

Now, we will begin writing text to a file:
1)- Create a new stream-writer and open the file:

Expand|Select|Wrap|Line Numbers

1. TextWriter tw = new StreamWriter(@"C:\Hello.txt");
2.  

2)- Write text to the file:

Expand|Select|Wrap|Line Numbers

1. tw.WriteLine("Hello");
2.  

3)- Close the file.

Expand|Select|Wrap|Line Numbers

1. tw.Close();
2.  

4)- Launch the file:

Expand|Select|Wrap|Line Numbers

1. Process.Start(@"C:\Hello.txt");
2.  

Here is all the code:

Expand|Select|Wrap|Line Numbers

1. //Creating a new stream-writer and opening the file.
2. TextWriter tsw = new StreamWriter(@"C:\Hello.txt");
3.  
4. //Writing text to the file.
5. tsw.WriteLine("Hello");
6.  
7. //Close the file.
8. tsw.Close();
9.  
10. //Launch the file.
11. Process.Start(@"C:\Hello.txt");
12.  
13. Console.WriteLine("You're done, press any key to exit...");
14. Console.ReadKey();
15.  

Now, we will begin reading text from a file:
1)- Creating a new stream-reader and opening the file:

Expand|Select|Wrap|Line Numbers

1. TextReader trs = new StreamReader(@"C:\Hello.txt");
2.  

2)- Reading text of the file:

Expand|Select|Wrap|Line Numbers

1. //Reading all the text of the file.
2. Console.WriteLine(trs.ReadToEnd());
3.  
4. //Or Can Reading a line of the text file.
5. //Console.WriteLine(trs.ReadLine());
6.  

3)- Close the file:

Expand|Select|Wrap|Line Numbers

1. trs.Close();
2.  

Here is all the code:

Expand|Select|Wrap|Line Numbers

1. //Creating a new stream-reader and opening the file.
2. TextReader trs = new StreamReader(@"C:\Hello.txt");
3.  
4. //Reading all the text of the file.
5. Console.WriteLine(trs.ReadToEnd());
6.  
7. //Or Can Reading a line of the text file.
8. //Console.WriteLine(trs.ReadLine());
9.  
10. //Close the file.
11. trs.Close();
12.  
13. Console.WriteLine("Press any key to exit...");
14. Console.ReadKey();
15.  

Hope this helped you.
